Template 6: Single Hazard - Cross-Zone NAC
• Output 4 = Release Stage Discharge - nonsilenceable, programmed Release Stage operation for
Release Circuit 1 (refer to "Cross-Zone for Release Circuit 1 or Release Circuit 2:" on
page 61)
Timers
• Pre-Discharge Delay - set for 30 seconds
• Discharge - set for Always On
• Waterflow Delay Timer - set for 90 seconds
• AC Loss Delay Timer - set for 2 hours
FACP Operation
• Input Zone 1 (2-Wire Smoke) Activation only:
Output 2 (Alarm NAC) will pulse 1 second on, 1 second off.
• Input Zone 2 (2-Wire Smoke) Activation only:
Output 2 (Alarm NAC) will pulse 1 second on, 1 second off.
• Input Zone 3 (Manual Release) Activation only:
Output 1 (Release Circuit 1) agent release remains on until reset.
Output 3 (Release Stage Pre-Discharge) will turn on steady.
Output 4 (Release Stage Discharge) will turn on steady.
• Input Zone 4 (Abort Release Switch) Activation only:
Pre-Discharge Timer will continue to count down until it reaches 10 seconds and then stop.
Releasing the Abort Release Switch will allow the Pre-Discharge Timer to continue its count
down from 10 second. If the Abort Release Switch is again activated before the Pre-Discharge
Timer reaches 0, the Timer will reset to 10 seconds and hold.
• Input Zone 5 (Discharge Pressure Switch) Activation:
Output 3 (Release Stage Pre-Discharge) will turn on steady.
Output 4 (Release Stage Discharge) will turn on steady
• Input Zone 6 (Supervisory) Activation only:
No output circuits will be activated. FACP will indicate a supervisory condition
• Input Zone 1 (2-Wire Smoke) and Input Zone 2 (2-Wire Smoke) Activation together:
In addition to the individual events that will occur for each Input Zone as detailed above, the
Pre-Discharge Timer will begin to count down. Output 2 will pulse and Output 3 will turn on
steady while the Pre-Discharge Timer is counting down. When the Pre-Discharge Timer
reaches 0, Output 1 (Release Circuit 1) will begin the agent release which will continue until
reset. Output 2 will turn on steady when the release begins. Output 4 will turn on steady to
indicate a discharge is in progress.
FACP Relay Operation
The following description of FACP relay operations are in addition to normal system operation.
• Alarm Relay (Latching) - activation of Input Zone 1 (2-Wire Smoke) or Zone 2 (2-Wire
Smoke) or Zone 3 (Manual Release) or Zone 5 (Discharge Pressure Switch) will operate Alarm
Relay
• Trouble Relay (Tracking) - any system trouble will activate the Trouble Relay
• Supervisory (Tracking) - activation Input Zone 6 (Supervisory), the disabling of Releasing
Circuit or any other system supervisory will operate the Supervisory Relay
